Install CentOS 7 on Software RAID

This is a quick video to show you how to install CentOS 7 on software RAID.

WANT TO SUPPORT ME & MOTIVATE ME TO MAKE MORE VIDEOS LIKE THIS?

ALSO, BECAUSE I GET ASKED AT LEAST ONCE ON EVERY VIDEO - "WHY/HOW ARE YOU VERIFIED? YOU HAVE LIKE A FEW HUNDRED SUBS!"
Back in 2011, I was one of the first to register for Google+ (yeah, remember that thing?) and at one point Google had a "verification" option to prove I was a real human and one day a "verified" check appeared next to my name. Then, Google decided to link everything to Google+, including YouTube. My account was of course linked and that carried my verification over. Fast forward several years and the meaning of verified went from "I am an actual human with this name" to "I am an elite status symbol". Well, because I was verified before Google changed the rules, I was allowed to keep my verification. I do not agree with reserving verification status to only the few who meet the criteria. Anyone (person or business) should be allowed to be verified so that others know they are who they say they are.

When I tried this on a baremetal Dell R720 with 400GB SAS SSDs (6Gbps), I received an error after clicking on the blue 'Done' button: "sdb may not have enough space for grub2 to embed core.img when using the ext4 file system on mdarray." Did a Google search with very little results. However I tried this on a 1.92TB SSD with no issues. The only problem here is I only have 400GB SSDs to use as system drives (and only one 1.92TB SSD) and I'm unsure if the problem is due to the small (400GB) size. However, I see this working well for you on a 40GB disk, so I'm not so sure what's going on here.

For CentOS7, to enable RAID during the installation, does it have to be using LVM for it to work?
